Re: Considering an AIS Transponder, any Recommendations?

While some early AIS splitters had troubles, that was a (relatively) long time ago. Sure a splitter could fail but so could a lot of other stuff.

The arguments for a modern splitter like the one from Vesper are pretty strong:

A: As mentioned, it lets you put the AIS antenna at the highest point substantially increasing your AIS receive and transmit range

B: The cost of a 2nd antenna is considerably more if you include good coax (LMR-400), an antenna mount, and - if you don't like drilling holes high in the air - installation.

C: The Vesper has several useful features including an amplifier to increase AIS reception range and an LED that shows you have a good antenna connection.

Re: Considering an AIS Transponder, any Recommendations?

The Si-Tex Metadata Class B AIS Transceiver caught my eye. It has a built-in GPS receiver. Seems like that would be a big plus, assuming there's a place to mount it that doesn't have much interference. I know fiberglass will block WiFi, but I don't think it does much to the frequency the GPS receiver uses.

Anyone have any experience with this model?

I'll second that. I have had one for two years of fairly constant use and I am very happy with it's performance.
